BACKGROUND Technical Field

This disclosure relates generally to a chassis for a multi-camera system.

Description of the Related Art

The advent of small, mobile multipurpose devices such as smartphones and tablet or pad devices has resulted in a need for high-resolution, small form factor cameras for integration in the devices. Some cameras may incorporate optical image stabilization (OIS) mechanisms that may sense and react to external excitation/disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compensate for unwanted motion of the lens. Furthermore, some cameras may incorporate an autofocus (AF) mechanism whereby the object focal distance can be adjusted to focus an object plane in front of the camera at an image plane to be captured by the image sensor. In some such AF mechanisms, the optical lens is moved as a single rigid body along the optical axis of the camera to refocus the camera.

This specification includes references to “one embodiment” or “an embodiment.” The appearances of the phrases “in one embodiment” or “in an embodiment” do not necessarily refer to the same embodiment. Particular features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.

“Comprising.” This term is open-ended. As used in the appended claims, this term does not foreclose additional structure or steps. Consider a claim that recites: “An apparatus comprising one or more processor units . . . .” Such a claim does not foreclose the apparatus from including additional components (e.g., a network interface unit, graphics circuitry, etc.).

“Configured To.” Various units, circuits, or other components may be described or claimed as “configured to” perform a task or tasks. In such contexts, “configured to” is used to connote structure by indicating that the units/circuits/components include structure (e.g., circuitry) that performs those task or tasks during operation. As such, the unit/circuit/component can be said to be configured to perform the task even when the specified unit/circuit/component is not currently operational (e.g., is not on). The units/circuits/components used with the “configured to” language include hardware—for example, circuits, memory storing program instructions executable to implement the operation, etc. Reciting that a unit/circuit/component is “configured to” perform one or more tasks is expressly intended not to invoke 35 U.S.C. § 112, sixth paragraph, for that unit/circuit/component. Additionally, “configured to” can include generic structure (e.g., generic circuitry) that is manipulated by software and/or firmware (e.g., an FPGA or a general-purpose processor executing software) to operate in manner that is capable of performing the task(s) at issue. “Configure to” may also include adapting a manufacturing process (e.g., a semiconductor fabrication facility) to fabricate devices (e.g., integrated circuits) that are adapted to implement or perform one or more tasks.

“First,” “Second,” etc. As used herein, these terms are used as labels for nouns that they precede, and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). For example, a buffer circuit may be described herein as performing write operations for “first” and “second” values. The terms “first” and “second” do not necessarily imply that the first value must be written before the second value.

“Based On.” As used herein, this term is used to describe one or more factors that affect a determination. This term does not foreclose additional factors that may affect a determination. That is, a determination may be solely based on those factors or based, at least in part, on those factors. Consider the phrase “determine A based on B.” While in this case, B is a factor that affects the determination of A, such a phrase does not foreclose the determination of A from also being based on C. In other instances, A may be determined based solely on B.

It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the intended scope. The first contact and the second contact are both contacts, but they are not the same contact.

The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

DETAILED DESCRIPTION

Various embodiments described herein relate to a chassis for use in conjunction with multiple cameras. In some examples, the chassis may provide a unitary body structure to which cameras may be attached or otherwise coupled, e.g., to form a multi-camera system module that may be incorporated into a device, such as a phone or other computing device. The chassis may comprise multiple chassis portions that each define a respective cavity for mounting a respective camera. For example, the chassis may comprise a first chassis portion to which a first camera is attached, and a second chassis portion to which a second camera is attached. The chassis may enable a reduced size of the system by integrating (e.g., into a monolithic component) that which in other systems may be multiple components. As a non-limiting example, one or more of the chassis portions may be shaped to serve as both a shield can (e.g., for a voice coil motor (VCM) actuator module of a camera) and a camera chassis (e.g., for supporting the camera in a multi-camera system), thus eliminating the need for a shield can that would otherwise be included as a separate component in some other systems.

According to various embodiments, the chassis may include one or more features, such as recess(es), pocket(s), cut-out(s), protrusion(s), variation(s) in wall thickness, etc. In some embodiments, such features may be realized by removing material (e.g., using a computer numerical control (CNC) machine) from a single piece of material (e.g., metal) to form a monolithic chassis that includes the features. Such features may be designed to, among other things, reduce overall system size, improve thermal performance (e.g., by shortening a thermal conduction path), reduce stray light risk (e.g., by reducing aperture size so as to reduce excess light ingress), simplify manufacturing (e.g., by reducing part count and/or eliminating process steps), improve structural integrity (e.g., by increasing stiffness of the chassis at portions with increased wall thickness), and/or accommodate particular camera profiles (e.g., based on design constraints and/or requirements), as discussed in further detail below.

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that some embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

As mentioned above, various embodiments include a chassis for mounting multiple cameras. FIGS. 1A-1E illustrate views of an example system 100 that includes an example of such a chassis 102 for mounting cameras. According to various embodiments, the chassis 102 may include one or more features (e.g., recess(es), pocket(s), cut-out(s), protrusion(s), and/or variation(s) in wall thickness, etc.) designed to, among other things, reduce overall system size, improve thermal performance (e.g., by shortening a thermal conduction path, as discussed herein with reference to FIG. 2B), reduce stray light risk (e.g., by reducing aperture size so as to reduce excess light ingress), simplify manufacturing (e.g., by reducing part count and/or eliminating process steps), improve structural integrity (e.g., by increasing stiffness of the chassis), and/or accommodate particular camera profiles (e.g., based on design constraints and/or requirements), as discussed herein. The example X-Y-Z coordinate system shown in FIG. 1A is used to discuss aspects of systems and/or system components, and may apply to embodiments described throughout this disclosure.

According to various embodiments, the system 100 may include the chassis 102, a first camera 104, and a second camera 106. The chassis 102 may include multiple respective portions to which respective cameras may be coupled. For example, the chassis 102 may include a first chassis portion 108 for mounting the first camera 104, and a second chassis portion 110 for mounting the second camera 106.

In some embodiments, the first chassis portion 108 may include a first top wall 112 and a first set of side walls (e.g., side walls 114 a-114 d). The first top wall 112 may define a first aperture 116. The first set of side walls may extend from the top wall 112. The first top wall 112 and the first set of side walls may define a first cavity for receiving at least a portion (e.g., a top portion) of the first camera 104, e.g., as indicated in FIGS. 1A-1B. The first chassis portion 108 may partially encase the first camera 104 when the first camera 104 is mounted to the chassis 102. The first set of side walls may include exterior side walls 114 a-114 c and an interior side wall 114 d. According to some embodiments, the interior side wall 114 d may extend from exterior side wall 114 a to exterior side wall 114 c (which is opposite exterior side wall 114 a). Furthermore, in some embodiments, the interior side wall 114 d may have a different wall thickness relative to at least one of the exterior side walls 114 a-114 c. In various embodiments, the interior side wall 114 d may be shared by the first chassis portion 108 and the second chassis portion 110.

In some embodiments, the second chassis portion 110 may include a second top wall 118 and a second set of side walls (e.g., side walls 120 a-120 d). The second top wall 118 may define a second aperture 122. The second set of side walls may extend from the second top wall 118. The second top wall 118 and the second set of side walls may define a second cavity for receiving at least a portion (e.g., a top portion) of the second camera 106, e.g., as indicated in FIGS. 1A-1B. The second chassis portion 110 may partially encase the second camera 106 when the second camera 106 is mounted to the chassis 102. The second set of side walls may include exterior side walls 120 a-120 c and an interior side wall 120 d. According to some embodiments, the interior side wall 120 d may extend from exterior side wall 120 a to exterior side wall 120 c (which is opposite exterior side wall 120 a). Furthermore, in some embodiments, the interior side wall 120 d may have a different wall thickness relative to at least one of the exterior side walls 120 a-120 c. As indicated above, the interior side wall 120 d may be shared by the first chassis portion 108 and the second chassis portion 110. For example, the interior side wall 120 d of the second chassis portion 110 may be the same wall as the interior side wall 114 d of the first chassis portion 108. For simplicity of discussion, the interior side wall, that is shared by the first chassis portion 108 and the second chassis portion 110, may also be referred to herein as the “shared interior side wall 114 d, 120 d”.

The shared interior side wall 114 d, 120 d may be located between the first cavity and the second cavity. In some examples, a first surface of the shared interior side wall 114 d, 120 d may at least partially delimit the first cavity, and a second surface (e.g., a surface facing opposite the first surface) of the shared interior side wall 114 d, 120 d may at least partially delimit the second cavity. According to some embodiments, the shared interior side wall 114 d, 120 d may be a solid wall between the first surface and the second surface. In some examples, the shared interior side wall 114 d, 120 d may comprise multiple different portions that respectively extend in the Z-axis direction by different amounts. For example, the shared interior side wall 114 d, 120 d may include a first portion that is closer to the first chassis portion 108 (than to the second chassis portion 110) and that extends more in the Z-axis direction than a second portion (of the shared interior side wall 114 d, 120 d) that is closer to the second chassis portion 110 (than to the first chassis portion 108), or vice-versa. In various embodiments, the geometry of the shared interior side wall 114 d, 120 d may be determined based at least in part on design constraints and/or design requirements with respect to one or more of the cameras and/or the overall system, such as relative placement of the cameras when mounted to the chassis 102, location and/or size of injection points for adhesive, and/or stiffness of the chassis 102, etc.

In some embodiments, the first top wall 112 may have a different wall thickness relative to the second top wall 118. As a non-limiting example, the first top wall 112 may be thicker than the second top wall 118, as indicated in FIG. 1A. In some embodiments, the top walls having different relative wall thicknesses may allow for the first camera 104 to be placed at a different height (e.g., in the Z-axis direction) relative to the second camera 106. The first top wall 112 may be parallel to the second top wall 118 in various examples.

As indicated in FIG. 1A, the first camera 104 may include a first lens barrel 124 that holds one or more lens elements (not shown). The lens element(s) may define a first optical axis 126. In some embodiments, the first lens barrel 124 may be at least partially disposed within the first aperture 116 when the first camera 104 is mounted to the chassis 102. Furthermore, the first camera 104 may include a first flex circuit 128 that conveys electrical signals (e.g., power and/or control signals) from one or more components to one or more other components. Similarly, the second camera 106 may include a second lens barrel 130 that holds one or more lens elements (not shown). The lens element(s) may define a second optical axis 132. In some embodiments, the second lens barrel 130 may be at least partially disposed within the second aperture 122 when the second camera 106 is mounted to the chassis 102. Furthermore, the second camera 106 may include a second flex circuit 134 that conveys electrical signals (e.g., power and/or control signals) from one or more components to one or more other components. The first camera 104 and/or the second camera 106 may include various other components (e.g., image sensor(s), substrate(s), actuator(s), etc.), some of which are discussed with reference to FIGS. 2A-2B.

In various embodiments, the system 100 may include one or more stiffeners that provide structural support to the first camera 104 and/or the second camera 106. For example, as indicated in FIG. 1A, a stiffener 136 may at least partially encase multiple sides of the first camera 104. As will be discussed in further detail below with reference to FIGS. 2A-2B, the stiffener 136 may include a base portion and one or more end portions. The end portion(s) may extend from the base portion and be oriented at a respective non-zero angle relative to the base portion. In various embodiments, each of one or more exterior side walls may define a respective recess for receiving a respective end portion of the stiffener 136, e.g., to connect the stiffener 136 to the chassis 102.

In a non-limiting example, exterior side wall 114 a may define a first recess within which at least part of a first end portion of the stiffener 136 may be disposed, and exterior side wall 114 c may define a second recess within which at least part of a second end portion of the stiffener 136 may be disposed. The first end portion and the second end portion may be connected to the chassis 102 at the first recess and the second recess, respectively, e.g., via an adhesive (not shown) disposed within the first recess and the second recess. In this example, a third end portion of the stiffener 136 may extend proximate a portion of exterior side wall 114 b, and/or a fourth end portion of the stiffener 136 may extend proximate a portion of exterior side wall 114 d. Furthermore, the third end portion of the stiffener 136 may be spaced apart from exterior side wall 114 b by a gap, and/or the fourth end portion of the stiffener 136 may be spaced apart from exterior side wall 114 d by a gap. As discussed herein with reference to FIG. 2B, some such arrangements for connecting a stiffener (e.g., stiffener 136) to a chassis (e.g., monolithic chassis 102) may shorten a thermal conduction path and improve thermal performance of the system.

As previously noted, one or more chassis portions may be shaped to serve as both a shield can and a camera chassis. As a non-limiting example, the chassis 102 may integrate a shield can and a chassis—which in other systems may be separate components that are attached to each other and/or to other components—into a monolithic component such as the first chassis portion 108 shown in FIGS. 1A-1E. In various embodiments, certain manufacturing process(es) may be used to enable the formation of an integrated shield can-chassis portion (e.g., the first chassis portion 108) of the chassis 102 and/or other features of the chassis 102. For example, one or more subtractive manufacturing processes may be used to form such features by removing material, e.g., from a piece of material.

By integrating the shield can and the chassis into one component, the size of the system 100 may be reduced. As a non-limiting example, an adhesive layer that would be used to attach the shield can to the chassis in some other systems, and that is eliminated in the system 100 due to the integration of the shield can and the chassis into one component, may enable a reduction in system dimension(s) in the X-axis and/or Y-axis direction(s). Furthermore, embodiments disclosed herein may improve the assembly process by reducing part count (e.g., by eliminating the separately formed shield can) and/or by eliminating a gluing assembly step that would be used to attach the separately formed shield can to the chassis in other systems.

In some examples, the use of subtractive manufacturing to form the chassis 102 may remove one or more constraints on material selection. For example, deep drawability may be a constraint that limits the materials that are considered in some other systems such as those in which the shield can and the shield can are separately formed via deep drawing. With such constraint(s) removed by using subtractive manufacturing, embodiments disclosed herein may allow for the consideration of a wider selection of materials.

The integration of multiple components into a single component and/or the use of subtractive manufacturing, in accordance with some embodiments disclosed herein, may enable the formation of one or more other features of the chassis 102 that may not be feasible in some other systems. For example, in some other systems in which deep drawn components are separately formed from respective sheets of material, the deep drawn components and/or the sheets of material may not provide sufficient material to form certain features in one or more regions of the material, e.g., a pocket formed in a top wall as discussed below.

In some embodiments, one or more of the top walls of the chassis 102 may define one or more pockets. For example, as shown in FIGS. 1A and 1C, one or more interior surfaces of the first top wall 112 may define one or more pockets 138. The interior surface(s) may be opposite at least one exterior surface of the first top wall 112. For example, an interior surface of the first top wall 112 may face towards an image sensor of the first camera 104, and an exterior surface may of the first top wall 112 may face away from the image sensor, such that the interior surface and the exterior surface face opposite directions. According to some embodiments, the pocket(s) 138 may be sized to accommodate at least a portion of an actuator (e.g., the actuator described herein with reference to FIGS. 2A-2B) of the first camera 104. The actuator may be configured to move a lens group and/or an image sensor of the first camera 104 in some embodiments. In some examples, the exterior surface(s) of the first top wall 112 may block light from passing to the image sensor via the pocket(s) 138.

According to various embodiments, the integration of the shield can and the chassis into a single component and/or the use of certain manufacturing process(es) (e.g., subtractive manufacturing) may enable formation of the pocket(s) 138 in the first top wall 112. In some other systems (e.g., one in which deep drawn components are separately formed from respective sheets of material), the formation of cut-out portions (instead of pocket(s) 138) that extend completely through a top wall may be required to accommodate the same component(s) (e.g., one or more portions of the actuator), which may effectively increase the size of an aperture and/or window on the top wall or otherwise increase the amount of light that may pass through the top wall to the image sensor, as compared to embodiments of the system 100 disclosed herein. Furthermore, by enabling a reduction in size of the first aperture 116, the formation of the pocket(s) 138 in the first top wall 112 may enable a tighter fit between the first lens barrel 124 and the first aperture 116, which may improve sealing in that region and/or reduce a particle ingress path, e.g., as compared to other systems that require cut-out portions on a top wall to accommodate the actuator.

In some embodiments, the chassis 102 may include one or more regions that vary in thickness and/or that have a different thickness relative to one or more other regions of the chassis 102. Additionally, or alternatively, one or more regions of the chassis 102 may have a respective thickness that provides a desired amount of stiffness (e.g., torsional and/or bending stiffness). In some embodiments, subtractive manufacturing may enable forming such region(s) of the chassis 102 to various thicknesses in accordance with design constraints and/or requirements. For example, as noted above, the geometry of the shared interior side wall 114 d, 120 d may be determined based at least in part on design constraints and/or design requirements with respect to one or more of the cameras and/or the overall system, such as relative placement of the cameras when mounted to the chassis 102, location and/or size of injection points for adhesive, and/or stiffness of the chassis 102, etc.

In a non-limiting example, the shared interior side wall 114 d, 120 d may define one or more pockets (e.g., one or more of the pockets indicated by arrows 140 in FIG. 1C) that provide location(s) at which adhesive may be injected to be introduced to gaps between surfaces disposed within the first cavity (defined by the first portion 108) and/or the second cavity (defined by the second portion 110). In some embodiments, the pocket(s) 140 may be sized to accommodate at least a portion of a needle used to inject the adhesive. Additionally, or alternatively, the pocket(s) 140 may be configured to provide a path along which the adhesive may flow to one or more desired locations.

In some embodiments, one or more chassis portions may comprise one or more corner protrusions each extending from a respective corner. As a non-limiting example, the first chassis portion 108 may have four corner protrusions 142 as indicated in FIGS. 1A and 1C. Each of the corner protrusions 142 may extend from a respective corner formed by a respective pair of adjacent side walls. In some embodiments, subtractive manufacturing may be used to form a corner protrusion 142 having an interior radius that is different than an exterior radius. However, the internal radius and the external radius of the corner protrusion 142 may be the same (or similar) in various embodiments. Additionally, or alternatively, the respective internal radius and/or external radius of one or more corner protrusions 142 may be the same as, similar to, and/or different than the respective internal radius and/or external radius of one or more other corner protrusions 142 in some embodiments. Additionally, or alternatively, the respective wall thickness of one or more corner protrusions 142 be the same as, similar to, and/or different than the respective wall thickness of one or more other corner protrusions 142 in some embodiments.

According to some embodiments, one or more chassis portions may include one or more grounding tabs, such as the grounding tab 144 shown in FIGS. 1A and 1C. The grounding tab 144 may extend from exterior side wall 114 b and an end portion of the grounding tab 144 may be connected to one or more components of the first camera 104 and/or the system 100 to provide at least a portion of an electrical grounding path.

FIG. 1D shows a top view of the chassis 102 with the first top wall 112 and the second top wall 118 uncovered. FIG. 1E indicates that a cover foam 146 may cover the first top wall 112 and the second top wall 118. In some embodiments, the cover foam 146 may be placed between top exterior surfaces of the chassis 102 and one or more other components located external to the system 100. The cover foam 146 may provide protection to the system 100 in certain cases, e.g., by functioning as a damper that mitigates damage from an impact in a drop event.

Various embodiments of the example system 100 shown in FIGS. 1A-1E may be described herein as having two chassis portions: the first chassis portion 108 and the second chassis portion 110. However, it is contemplated that the system 100 may include more than two chassis portions in some embodiments. As a non-limiting example, the system 100 may include a third chassis portion (not shown) in addition to the first chassis portion 108 and the second chassis portion 110. A chassis having three chassis portions may be T-shaped in some embodiments. One or more of the chassis portions may be an integrated shield can-chassis portion like the first chassis portion 108 described herein. The system 100 may not include a separately formed shield can between the first chassis portion 108 (and/or other integrated shield can-chassis portions) and the first camera 104 (and/or other cameras corresponding to other integrated shield can-chassis portions).

In various embodiments, the first camera 104 may be different than the second camera 106 (and/or one or more other cameras of the system 100) with respect to one or more characteristics. As a non-limiting example, the first camera 104 may have a first focal length that is different than a second focal length of the second camera 106. As another non-limiting example, the first camera 104 may have a first field of view that is different than a second field of view of the second camera 106. In some embodiments, the first camera 104 may be a first camera module of a first size, and the second camera 106 may be a second camera module of a second size that is different (e.g., with respect to one or more dimensions) than the first size. In other embodiments, the first camera 104 and the second camera 106 may be the same (or similar) in size and/or other characteristics (e.g., focal length, field of view, etc.).

FIGS. 2A-2B illustrate cross-sectional views of an example system 200 that includes a camera mounted in a portion of a chassis 202, in accordance with some embodiments. In various examples, the chassis 202 may be the same as (or similar to) the chassis 102 described above with reference to FIGS. 1A-1E. According to various embodiments, the camera may include a lens group 204, an image sensor 206, a substrate 208, and/or an actuator. The lens group 204 may comprise one or more lens elements (e.g., lens element 210) that define an optical axis. The image sensor 206 may be configured to capture light that has passed through the lens group 204. The image sensor 206 may be attached to the substrate 208.

In some embodiments, the camera may include a lens barrel 212 within which the lens group 204 is held. Furthermore, in some embodiments, the camera may include a lens carrier 214 that is coupled with the lens barrel 212 and/or the lens group 204. For example, the lens carrier 214 may be coupled with the lens barrel 212 and/or the lens group 204 such that the lens carrier 214, the lens barrel 212, and/or the lens group 204 are movable (e.g., via the actuator) together (e.g., in lockstep).

According to various embodiments, the actuator may be configured to move the lens group 204 relative to the image sensor 206. Additionally, or alternatively, the actuator may be configured to move the image sensor 206 relative to the lens group 204. In various examples, the actuator may be used to provide autofocus (AF) and/or optical image stabilization (OIS) functionality. In some embodiments, the actuator may comprise a VCM actuator with an arrangement of one or more magnets and one or more coils. The magnet(s) may magnetically interact with the coil(s) to produce Lorentz forces that cause movement of one or more components of the camera, e.g., for AF and/or OIS purposes.

As indicated in FIGS. 2A-2B, the camera may include a magnet holder 216 to which one or more magnets 218 of the actuator may be attached. One or more AF coils 220 of the actuator may be attached to the lens carrier 214. The AF coil(s) may be located proximate the magnet(s) 218 so that they can magnetically interact, e.g., to provide AF movement (e.g., movement along the optical axis) of the lens group 204 relative to the image sensor 206. In some embodiments, the actuator may include one or more OIS coils 222 located proximate the magnet(s) 218 (e.g., below the magnet(s) 218) so that they can magnetically interact, e.g., to provide OIS movement (e.g., movement in one or more directions orthogonal to the optical axis) of the lens group 204 relative to the image sensor 206. In this non-limiting example, the OIS coil(s) 222 may be disposed on a stationary structure that is stationary relative to movement of the lens group 204 in some embodiments.

According to various embodiments, the chassis 202 may at least partially encase the camera. Furthermore, the system 200 may include a stiffener 224 that may at least partially encase the camera. In some embodiments, the chassis 202 may encase a first portion (e.g., an upper portion) of the camera, and the stiffener 224 may encase a second portion (e.g., a lower portion) of the camera. In various embodiments, the first portion and the second portion may overlap in one or more regions at which the stiffener 224 overlaps with the chassis 202 (e.g., region(s) at which the stiffener 224 may be attached to the chassis 202).

In some embodiments, the chassis 202 may include one or more top walls 226 and one or more side walls 228. In some non-limiting examples, the top wall(s) 226 may extend proximate to (e.g., above) the actuator (and/or another portion of the camera) such that the top wall(s) 226 at least partially encase the actuator and the camera from above. Additionally, or alternatively, the side wall(s) 228 may extend proximate to (e.g., alongside) respective sides of the actuator (and/or respective sides of the camera) such that the side wall(s) 228 at least partially encase sides of the actuator and the camera.

In some embodiments, the stiffener 224 may include a base portion 230 and one or more end portions 232. The base portion 230 may extend proximate (e.g., below) to the substrate 208 and/or parallel to the image sensor 206 in some embodiments. The end portion(s) 232 may extend from the base portion 230. Furthermore, each of the end portion(s) 232 may be oriented at a respective non-zero angle relative to the base portion 230. In a non-limiting example, the end portion(s) 232 may be orthogonal to the base portion 230. The base portion 230 may at least partially encase the camera from below. The end portion(s) 232 may extend proximate to (e.g., alongside) respective sides of the camera such that the end portion(s) 232 at least partially encase sides of the camera. According to some non-limiting examples, the stiffener 224 may be considered a folded stiffener that is formed, e.g., by folding a piece of material (e.g., a sheet of metal). In some examples, the piece of material may be cut (e.g., via etching) into a particular shape including the base portion 230 and tabs extending from the base portion 230 that can be folded to form the end portions 232.

According to various embodiments, one or more of the side walls 228 of the chassis 202 may define a respective recess 234 for receiving a respective end portion 232 of the stiffener 224. In some embodiments, a side wall 228 may comprise a first portion 244 having a first wall thickness, and a second portion 250 that extends from the first portion and that has a second wall thickness that is greater than the first wall thickness, e.g., as indicated in FIGS. 2A-2B. For example, the first portion 244 of the side wall 228 may include an exterior surface 242 of the recess 234 to which an end portion 232 of the stiffener 224 may be attached, e.g., via an adhesive 236 disposed within the recess 234 as indicated in FIG. 2B. In some embodiments, the end portion 232 of the stiffener 224 may be biased towards the corresponding side wall 228 to which it is attached. In some non-limiting embodiments, the recess 234 may be sized such that it may contain the adhesive 236, with the end portion 232 of the stiffener 224 being disposed within the recess 234 such that an external surface of the end portion 232 is flush with an exterior surface 252 of the second portion 250 of the side wall 228.

FIG. 2B includes a schematic overlay of an example thermal conduction path 238 of the system 200. The thermal conduction path 238 may represent a path along which heat may be dissipated in some embodiments. As a non-limiting example, heat produced by one or more components (e.g., the image sensor 206, the OIS coil(s) 222, a motor driver 240 for controlling the actuator, etc.) of the camera may travel along the thermal conduction path and be dissipated from the chassis 202 to an environment external to the chassis 202.

As indicated in FIG. 2B, the thermal conduction path 238 may include heat transferring from the stiffener 224 to the chassis 202 via the adhesive 236 disposed within the recess 234. In various embodiments, the adhesive 236 disposed within the recess 234 may be the only intervening material, in the heat conduction path 238, between the stiffener 224 and the chassis 202. In some other systems (e.g., in which the shield can and the chassis are formed separately, as discussed above), an adhesive layer would be used to attach the shield can to the chassis, meaning that such other systems would include at least two additional intervening materials (e.g., the separately formed shield can and the adhesive used to attach it to the chassis) to the corresponding thermal conduction path. Compared to those other systems, the thermal conduction path 238 of the system 200 may be shortened, as the chassis 202 may comprise one or more integrated shield can-chassis portions, thus eliminating the need for the separately formed shield can and the additional adhesive layer of the other systems. The shortened thermal conduction path 238 may improve thermal performance of the system 200 compared to other systems having the longer thermal conduction path.

FIG. 3 is a flow chart of an example method 300 for manufacturing a chassis (e.g. which may include one or more features of the chassis 102 described herein with reference to FIGS. 1A-1E and/or the chassis 202 described herein with reference to FIGS. 2A-2B) for mounting multiple cameras, in accordance with some embodiments. It should be understood that the operations of the method 300 are not necessarily performed in the order in which they are described. That is, the operations of the method 300 may be performed in one or more different orders in accordance with various implementations. Furthermore, it should be understood that one or more of the operations described herein may be omitted in some implementations. Similarly, it should be understood that the operations described herein are not an exhaustive list of operations that may be included in the method 300. It is contemplated that fewer or additional (and/or different) operations than those described herein may be performed in various embodiments.

At 302, the method 300 may include removing portions(s) from a piece of material to form the chassis for mounting multiple cameras. In various implementations, the method 300 may include one or more operations of removing material from a same piece of material, e.g., via subtractive manufacturing such as (but not limited to) CNC machining.

According to various examples, at 304, the method 300 may include forming cavities for receiving cameras. In some implementations, at 306, the method 300 may include removing material, from the piece of material, to form a first cavity for receiving a first camera. For example, the first cavity may be at least partially defined by a first top wall and a first set of side walls of a first chassis portion. The first chassis portion may be structured to partially encase the first camera when the first camera is mounted to the chassis. In some implementations, at 308, the method 300 may include removing material, from the piece of material, to form a second cavity for receiving a second camera. For example, the second cavity may be at least partially defined by a second top wall and a second set of side walls of a second chassis portion. The second chassis portion may be structured to partially encase the second camera when the second camera is mounted to the chassis. In some embodiments, the first top wall may have a different wall thickness relative to the second top wall.

At 310, the method 300 may include forming an interior side wall, e.g., via formation of the first cavity (at 306) and/or formation of the second cavity (at 308), according to some implementations. In some examples, a portion of the interior side wall may be formed as a result of forming the first cavity (at 306) and/or forming the second cavity (at 308), and one or more features (e.g., recess(es), pocket(s), protrusion(s), etc.) may be defined on the interior side wall in another material removal operation, e.g., at 312, where the method 300 may include removing material, from the piece of material, to form at least a portion of the interior side wall. In some embodiments, the interior side wall may have a different wall thickness relative to at least one side wall of the first set of side walls and/or relative to at least one side wall of the second set of side walls.

At 314, the method 300 may include forming aperture(s) in the top wall(s). For example, a first aperture may be formed in the first top wall that partially defines the first cavity, and a second aperture may be formed in the second top wall that partially defines the second cavity. The first aperture may be configured to receive at least a portion of the first camera (e.g., a lens barrel of the first camera). The second aperture may be configured to receive at least a portion of the second camera (e.g., a lens barrel of the second camera).

At 316, the method 300 may include forming pocket(s) in the top wall(s). For example, the pocket(s) may be configured to accommodate at least a portion of an actuator of the first camera and/or the second camera in some embodiments. According to some examples, a pocket may be defined by one or more interior surfaces of a top wall. The interior surface(s) may be opposite at least one exterior surface of the top wall.

At 318, the method 300 may include forming recess(es) in side wall(s). For example, material may be removed, from the piece of material, to form a recess defined by a side wall of the first set of side walls or the second set of side walls, such that a first portion of the side wall has a different wall thickness relative to a second portion of the side wall due to the recess. As described herein with reference to FIGS. 1A-2B, the recess may be configured to receive an end portion of a stiffener that at least partially encases the first camera and/or the second camera. Adhesive may be disposed within the recess to attach the end portion of the stiffener to the chassis.

Attention is now directed toward embodiments of portable devices with cameras. FIG. 4 illustrates a block diagram of an example portable multifunction device 400 that may include a chassis for mounting multiple cameras (e.g., the chassis and/or camera(s) described above with reference to FIGS. 1A-3), in accordance with some embodiments. Cameras 464 are sometimes called “optical sensors” for convenience, and may also be known as or called an optical sensor system. Device 400 may include memory 402 (which may include one or more computer readable storage mediums), memory controller 422, one or more processing units (CPUs) 420, peripherals interface 418, RF circuitry 408, audio circuitry 410, speaker 411, touch-sensitive display system 412, microphone 413, input/output (I/O) subsystem 406, other input or control devices 416, and external port 424. Device 400 may include multiple optical sensors 464. These components may communicate over one or more communication buses or signal lines 403.

It should be appreciated that device 400 is only one example of a portable multifunction device, and that device 400 may have more or fewer components than shown, may combine two or more components, or may have a different configuration or arrangement of the components. The various components shown in FIG. 4 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 402 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 402 by other components of device 400, such as CPU 420 and the peripherals interface 418, may be controlled by memory controller 422.

Peripherals interface 418 can be used to couple input and output peripherals of the device to CPU 420 and memory 402. The one or more processors 420 run or execute various software programs and/or sets of instructions stored in memory 402 to perform various functions for device 400 and to process data.

In some embodiments, peripherals interface 418, CPU 420, and memory controller 422 may be implemented on a single chip, such as chip 404. In some other embodiments, they may be implemented on separate chips.

RF (radio frequency) circuitry 408 receives and sends RF signals, also called electromagnetic signals. RF circuitry 408 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry 408 may include well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry 408 may communicate with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The wireless communication may use any of a variety of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSDPA), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

Audio circuitry 410, speaker 411, and microphone 413 provide an audio interface between a user and device 400. Audio circuitry 410 receives audio data from peripherals interface 418, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 411. Speaker 411 converts the electrical signal to human-audible sound waves. Audio circuitry 410 also receives electrical signals converted by microphone 413 from sound waves. Audio circuitry 410 converts the electrical signal to audio data and transmits the audio data to peripherals interface 418 for processing. Audio data may be retrieved from and/or transmitted to memory 402 and/or RF circuitry 408 by peripherals interface 418. In some embodiments, audio circuitry 410 also includes a headset jack (e.g., 512, FIG. 5). The headset jack provides an interface between audio circuitry 410 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 406 couples input/output peripherals on device 400, such as touch screen 412 and other input control devices 416, to peripherals interface 418. I/O subsystem 406 may include display controller 456 and one or more input controllers 460 for other input or control devices. The one or more input controllers 460 receive/send electrical signals from/to other input or control devices 416. The other input control devices 416 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 460 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 508, FIG. 5) may include an up/down button for volume control of speaker 411 and/or microphone 413. The one or more buttons may include a push button (e.g., 506, FIG. 5).

Touch-sensitive display 412 provides an input interface and an output interface between the device and a user. Display controller 456 receives and/or sends electrical signals from/to touch screen 412. Touch screen 412 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.

Touch screen 412 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 412 and display controller 456 (along with any associated modules and/or sets of instructions in memory 402) detect contact (and any movement or breaking of the contact) on touch screen 412 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 412. In an example embodiment, a point of contact between touch screen 412 and the user corresponds to a finger of the user.

Touch screen 412 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 412 and display controller 456 may detect contact and any movement or breaking thereof using any of a variety of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 412. In an example embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch screen 412 may have a video resolution in excess of 800 dpi. In some embodiments, the touch screen has a video resolution of approximately 860 dpi. The user may make contact with touch screen 412 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 400 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen 412 or an extension of the touch-sensitive surface formed by the touch screen.

Device 400 also includes power system 462 for powering the various components. Power system 462 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 400 may also include one or more optical sensors or cameras 464. FIG. 4 shows an optical sensor 464 coupled to optical sensor controller 458 in I/O subsystem 406. Optical sensor 464 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 464 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 443 (also called a camera module), optical sensor 464 may capture still images or video. In some embodiments, an optical sensor 464 is located on the back of device 400, opposite touch screen display 412 on the front of the device, so that the touch screen display 412 may be used as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display.

Device 400 may also include one or more proximity sensors 466. FIG. 4 shows proximity sensor 466 coupled to peripherals interface 418. Alternately, proximity sensor 466 may be coupled to input controller 460 in I/O subsystem 406. In some embodiments, the proximity sensor 466 turns off and disables touch screen 412 when the multifunction device 400 is placed near the user's ear (e.g., when the user is making a phone call).

Device 400 includes one or more orientation sensors 468. In some embodiments, the one or more orientation sensors 468 include one or more accelerometers (e.g., one or more linear accelerometers and/or one or more rotational accelerometers). In some embodiments, the one or more orientation sensors 468 include one or more gyroscopes. In some embodiments, the one or more orientation sensors 468 include one or more magnetometers. In some embodiments, the one or more orientation sensors 468 include one or more of global positioning system (GPS), Global Navigation Satellite System (GLONASS), and/or other global navigation system receivers. The GPS, GLONASS, and/or other global navigation system receivers may be used for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 400. In some embodiments, the one or more orientation sensors 468 include any combination of orientation/rotation sensors. FIG. 4 shows the one or more orientation sensors 468 coupled to peripherals interface 418. Alternately, the one or more orientation sensors 468 may be coupled to an input controller 460 in I/O subsystem 406. In some embodiments, information is displayed on the touch screen display 412 in a portrait view or a landscape view based on an analysis of data received from the one or more orientation sensors 468.

In some embodiments, the software components stored in memory 402 include operating system 426, communication module (or set of instructions) 428, contact/motion module (or set of instructions) 430, graphics module (or set of instructions) 432, text input module (or set of instructions) 434, Global Positioning System (GPS) module (or set of instructions) 435, arbiter module 458 and applications (or sets of instructions) 436. Furthermore, in some embodiments memory 402 stores device/global internal state 457. Device/global internal state 457 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 412; sensor state, including information obtained from the device's various sensors and input control devices 416; and location information concerning the device's location and/or attitude.

Operating system 426 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 428 facilitates communication with other devices over one or more external ports 424 and also includes various software components for handling data received by RF circuitry 408 and/or external port 424. External port 424 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector.

Contact/motion module 430 may detect contact with touch screen 412 (in conjunction with display controller 456) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 430 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 430 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 430 and display controller 456 detect contact on a touchpad.

Contact/motion module 430 may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

Graphics module 432 includes various known software components for rendering and displaying graphics on touch screen 412 or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

In some embodiments, graphics module 432 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module 432 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 456.

Text input module 434, which may be a component of graphics module 432, provides soft keyboards for entering text in various applications (e.g., contacts 437, e-mail 440, IM 441, browser 447, and any other application that needs text input).

GPS module 435 determines the location of the device and provides this information for use in various applications (e.g., to telephone 438 for use in location-based dialing, to camera 443 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).
